CCNP-BSCI-v5.0 Lab 2-1: 基本EIGRP設定

本次練習是參考Cisco網路學院
CCNP1 Building Scalable Internetworks v5.0
Student Lab Manual
我將它轉成Dynamips的設定檔 並寫下自己的實驗紀錄


Dynamips的設定檔:

這Lab只是基本EIGRP設定練習

我的設定是
1. 先設定R1-3每個介面的ip address
R1:
hostname R1
!
no ip domain lookup
!
interface Loopback1
 ip address 10.1.1.1 255.255.255.0
!       
interface FastEthernet0/0
 description R1-SW1
 ip address 10.1.100.1 255.255.255.0
 no shutdown
!       
interface Serial1/0
 description R1-R2
 ip address 10.1.200.1 255.255.255.0
 no shutdown
!
line con 0
 logging synchronous
!
end

R2:
hostname R2
!
no ip domain lookup
!
interface Loopback2
 ip address 10.1.2.1 255.255.255.0
!       
interface FastEthernet0/0
 description R2-SW1
 ip address 10.1.100.2 255.255.255.0
 no shutdown
!
interface Serial1/0
 description R2-R1
 ip address 10.1.200.2 255.255.255.0
 no shutdown
!
line con 0
 logging synchronous
!
end

R3:
hostname R3
!
no ip domain lookup
!
interface Loopback1
 ip address 192.168.100.1 255.255.255.252
!       
interface Loopback3
 ip address 10.1.3.1 255.255.255.0
!
interface Loopback15
 ip address 192.168.100.5 255.255.255.252
!
interface FastEthernet0/0
 description R3-SW1
 ip address 10.1.100.3 255.255.255.0
 no shutdown
!
line con 0
 logging synchronous
!
end


2. 設定整個10.0.0.0網段的EIGRP
R1:
router eigrp 1
 network 10.0.0.0

R2:
router eigrp 1
 network 10.0.0.0

R3:
router eigrp 1
 network 10.0.0.0

3. R3上設定Loopback1跑EIGRP 但Loopback15不跑EIGRP
R3:
router eigrp 1
 network 192.168.100.0 0.0.0.3

4. 會發現R1-2的路由表 關於R3的Loopback1 資訊並不正確
R1-2:
D    192.168.100.0/24 [90/156160] via 10.1.100.3, 00:00:08, FastEthernet0/0
為什麼??因為Cisco預設ERIGRP會auto-summary
R3: no auto-summary 就OK了

5. 驗證指令
show ip eigrp neighbors
show ip route eigrp
ping


R1設定檔:
hostname R1
!
no ip domain lookup
!
interface Loopback1
 ip address 10.1.1.1 255.255.255.0
!       
interface FastEthernet0/0
 description R1-SW1
 ip address 10.1.100.1 255.255.255.0
!
interface Serial1/0
 description R1-R2
 ip address 10.1.200.1 255.255.255.0
!
router eigrp 1
 network 10.0.0.0
!
line con 0
 logging synchronous
!
end

R2設定檔:
hostname R2
!
no ip domain lookup
!
interface Loopback2
 ip address 10.1.2.1 255.255.255.0
!       
interface FastEthernet0/0
 description R2-SW1
 ip address 10.1.100.2 255.255.255.0
!
interface Serial1/0
 description R2-R1
 ip address 10.1.200.2 255.255.255.0
!
router eigrp 1
 network 10.0.0.0
!
line con 0
 logging synchronous
!
end

R3設定檔:
hostname R3
!
no ip domain lookup
!
interface Loopback1
 ip address 192.168.100.1 255.255.255.252
!       
interface Loopback3
 ip address 10.1.3.1 255.255.255.0
!
interface Loopback15
 ip address 192.168.100.5 255.255.255.252
!
interface FastEthernet0/0
 description R3-SW1
 ip address 10.1.100.3 255.255.255.0
!
router eigrp 1
 network 10.0.0.0
 network 192.168.100.0 0.0.0.3
!
line con 0
 logging synchronous
!
!
